The Annulus Circle App computes the number of square units it takes to completely fill an annulus. This area is computed from an Outer Radius and Inner Radius whereby: Area = π(R1² - R2²)
This app also computes a quadratrure rule whereby for the computed result: R1² <= Computed Result <= R2².
A graphical representation of the circle radii and area is presented.
Annulus circle has versions for iPad, iPhone and Apple Watch.
